Energy-Creating Pilot Project Saves Money

The District is embarking on an exciting new pilot project that has the potential to create more energy and reduce the amount of biosolids material we currently have to haul off-site. In the wastewater treatment process, energy is created through the digestion of organic material by helpful bacteria, leaving a substance known as biosolids.

These digested biosolids are typically hauled off-site for reuse. These same biosolids can be further processed and sent back to the digesters a second time to produce more gas and energy, while reducing the amount hauled away. The result is that we’ll haul fewer biosolids off-site in trucks, and we’ll reduce our demand for grid energy. This helps the environment by reducing greenhouse gases (GHGs), and it lowers GSD’s cost for hauling and electricity.
